The costs of flying are extremely costly. There are very little ways to make money as a pilot in the aviation community unless you have a Commercial pilot certificate. As a Commercial Pilot you have the ability to charge for the services you provide. In order to be eligible for this certificate, you must hold at least a private pilot certificate and hold at least a 2nd class medical. Other requirements are listed in part §61.121.
                        This license can be obtained any time after you receive your private pilot certificate, assuming you have met all of the prerequisites. Some pilots get their commercial certificate before their instrument rating to help cover the costs of their flight training. They are able to do this because a commercial certificate can be received for any type of aircraft. As you learn to fly more complex aircrafts you will have to get type rated in order to keep your commercial certificate current.
                       As with the private pilot certificate there are limitations with this certificate. There is only one pertaining to an airplane category or powered lift category. The limitation prevents a commercial pilot certificate holder, who does not hold an instrument rating, from flying in excess of 50nm and at night when carrying passengers. A full list and clarification of each limitation can be found in part §61.133
                       Once you receive your commercial certificate, you will be able to earn some of the well spent training money back. The next step is to become an Airline Transport Pilot (ATP).
